Once you've signed in to YouTube with your Google Account, you can create a YouTube channel on your account. YouTube channels let you upload videos, leave comments, and create playlists. Run an Internet speed test to make sure that your Internet can support the selected video resolution. Using multiple devices on the same network may reduce the speed that your device gets. You can also change the quality of your video to improve your experience. Check the YouTube video's resolution and the recommended speed needed to play the video. The table below shows the approximate speeds recommended to play each video resolution. 说一下我粗浅的理解吧，不一定对，以后再修改。 Born-Oppenheimer (BO)近似于分子动力学 (MD)更像是底层的逻辑基础。 对稍大体系，量子处理的计算量不可承受，因此现在主流的MD还是基于牛顿力学的。一个主要的假设是将分子粗粒化到只剩下核，核在势场中运动。 BO近似描绘的物理图景就是这样的 ...
